Even in television, the electronic picture frame function can be implemented.

Hereinafter, a preferred embodiment of a well paper image output device and method according to the present invention will be described in detail with reference to the accompanying drawings.

The present invention is applied to various types of broadcast receivers, for example, a set top box (STB) for receiving digital broadcasts or an IP set-top box (IP-STB) for receiving digital broadcasts and IP broadcasts.

On the other hand, the IP set-top box to which the present invention is applied is used in connection with the television 100, for example, as shown in FIG. 1, but the television 100 is not equipped with an electronic picture frame function. A television is used, and any other A / V devices such as a DVD player 300 or the like are connected to the television.

In addition, the IP set-top box 200 includes a tuner module and a network module, as well as a VOD service through a network 400 such as the Internet. It is connected to the content providing server 500 that provides the IP broadcasting service.

The IP set-top box 200 includes, for example, a tuner module 20, a digital signal processor 21, an interface module 22, a microcomputer 23, and an A / V as illustrated in FIG. 2. The decoder 24, the timer 25, the storage 26, and the network module 27 are included.

The storage 26 may be, for example, a large-capacity recording medium such as a hard disk (HDD), or various types of nonvolatile memory such as a flash memory, and the like. ), An external storage such as a USB card used in connection with the IP set-top box may be used.

In addition, in the storage 26, as shown in FIG. 3, the well paper information is stored and managed as a database in the form of a lookup table. There are a plurality of well paper entries (Wall Paper Entry # 1, # 2, # 3 ...) stored separately.

Meanwhile, each of the well paper entries includes at least one well paper image data (eg, abc1.jpg, abc2.jpg ...) and is stored in addition to text of a message arbitrarily set by a user. ) Data and date information, etc., are stored in association as optional information.

The date information is for designating a specific date on which the well paper image data is to be displayed, and a wedding anniversary, birthday, or national holiday, which the user arbitrarily designates, is stored as date information.

On the other hand, in the microcomputer 23, for example, in response to a user's request, the digital signal processor 21, the A / V decoder 24, and the like are operated to control a part of the video data of digital broadcasting or IP broadcasting. After capturing the video data, at least one still image may be stored as well paper image data (eg, abc1.jpg), or video data of some videos may be stored as well paper image data (eg, xyz1.avi).

Accordingly, the well paper information stores and manages a plurality of well paper entries in which well paper image data of at least one still image or a partial video and additional information such as text data and date of a message set by a user are grouped together. .

In the microcomputer 23, if the well paper mode is set while outputting audio and video of a broadcast program received through digital broadcasting or IP broadcasting to a television, the microcomputer 23 stores the well paper previously stored and managed. The image data is read and reproduced, and a corresponding well paper image is output to the television, which will be described in detail as follows.

4 is a flowchart illustrating an embodiment of a method for outputting a well paper image according to the present invention. In the microcomputer 23, the microcomputer 23 is connected to the television 100 through the interface module 22. In operation S10, when digital broadcasting is received through the tuner module 20, the digital signal processor 21 is controlled to output audio and video data of a digital broadcasting program to the television 100. .

In addition, when receiving the IP broadcast via the network module 27, the microcomputer 23 operates to control the A / V decoder 24 to transfer audio and video data of the IP broadcast program to the television. It is output (S11).

Then, while outputting the audio and video of the broadcast program received through digital broadcasting or IP broadcasting to the television as described above, the user inputs a user key for setting the well paper mode, or the received broadcast program is If there is no user key input so that a predetermined time (eg, 10 seconds) elapses after the termination, the microcomputer 23 automatically sets the well paper mode.

On the other hand, when the well paper mode is set (S12), the microcomputer 23 searches for the well paper information stored in the storage 26 and reads any one well paper image data. The / V decoder 24 is operated to output the well paper image corresponding to the image data to the television 100 connected and connected through the interface module 22 (S13).

In addition, the microcomputer 23 switches the operation mode of the IP set-top box to an idle state (S14). For example, when the idle state is set as described above, the micom 23 reproduces and outputs a well paper image. The unnecessary tuner module 20, the digital signal processor 21, the network module 27, and the like are disabled to prevent unnecessary power consumption.

Accordingly, the screen of the television connected and connected through the interface module 22 does not display a black screen or a blue screen without a signal as shown in FIG. 5, but is output from the IP set-top box. The well paper image is displayed to perform an electronic picture frame function. In the well paper image, today's date (for example, May 25) and the like may be displayed as text.

On the other hand, in the microcomputer 23, today's date counted by the timer 25 is, for example, May 9, and is recorded in a first well paper entry (Wall Paper # 1) of the well paper information. If the date information is May 9, the image data recorded in the first well paper entry is read and reproduced and output to the television.

Accordingly, as shown in FIG. 6, for example, a well paper image (eg, a wedding anniversary photo) corresponding to May 9 of the present day is displayed on the screen of the television. If the text data linked and recorded as additional information in the paper entry is " Wedding Anniversary ", a corresponding message is superimposed and displayed on the well paper image.

In addition, in the microcomputer 23, when there are a plurality of image data recorded in the first well paper entry (for example, abc1.jpg, abc2.jpg ...), the predetermined count is counted by the timer 25. By reading and reproducing the image data sequentially and outputting the image data to the television at a time interval (for example, 30 seconds), a new well paper image is alternately displayed on the television screen as shown in FIG.

Meanwhile, while performing a series of operations of outputting a well paper image as described above, the microcomputer 21 monitors whether the TV connected via the interface module 22 is powered off or the TV input mode is changed. (S17).

For example, when the user turns off the power of the television or changes the input mode of the television to the DVD player 300 (S18), the microcomputer 21 automatically changes the well paper mode. In addition to the release, the power of the IP set-top box is automatically turned off (S17).

On the other hand, in the microcomputer 23, when a user key for requesting broadcast reception is input in the idle state (S18), the microcomputer 23 automatically releases the well paper mode and the idle state and corresponds to the user key input. The broadcast reception operation is performed to output video and audio data of a digital broadcast or IP broadcast program to the television (S19).

Accordingly, the black screen or the blue screen in the no signal state can be prevented from being displayed on the screen of the television, and the electronic picture frame function can be implemented even in a general television which is not equipped with the electronic picture frame function.

Meanwhile, in the well paper information, predetermined audio data (for example, music) may be cooperatively stored together with the image data. In this case, a well paper image is displayed on the screen of the television, and the television is displayed. Through the speaker, audio such as music can be output.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. , Alteration, substitution, addition, or the like.
